While I agree with you here, I feel like people don't try to optimize an already working base. For example, I recently updated the clock app on my android phone. There is no difference in functionality in the new app, but it has the android 12 design. This time could have been spent optimizing the app in a way or another. I do the same thing on my phone as I did 5/6 years ago: read a lot online, sometimes listen to music, sometimes look at maps, sometimes use apps, telephony. My battery lasts longer these days, but not as much because my phone also has to show sweet animations and be able to run high-performance stuff (I made the error of buying a flagship phone).
